如何解析 java.lang.LinkageError org.bouncycastle.mail.smime.SMIMESignedGenerator.generate(Ljavax/mail/internet/MimeBodyPart;)
How to resolve java.lang.LinkageError org.bouncycastle.mail.smime.SMIMESignedGenerator.generate(Ljavax/mail/internet/MimeBodyPart;)
我将 Bouncycastle（bcmail、bcprov、bcpkix）1.57 与 Jboss EAP 6.4（jboss-AS 7.5）和 Java 1.8 结合使用。
我收到以下堆栈跟踪的链接错误：
Caused by: java.lang.LinkageError:
loader constraint violation: when resolving method "org.bouncycastle.mail.smime.SMIMESignedGenerator.generate(Ljavax/mail/internet/MimeBodyPart;)Ljavax/mail/internet/MimeMultipart;"
the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, de/deutschepost/paket/mkp/transformation/SMIMEPreparator,
and the class loader (instance of org/jboss/modules/ModuleClassLoader) for the method's defining class, org/bouncycastle/mail/smime/SMIMESignedGenerator,
have different Class objects for the type javax/mail/internet/MimeBodyPart used in the signature
据我所知，层次结构中某处的库版本一定存在重复或冲突，但不幸的是我找不到。

此问题是由于 multiple javax-mail versions 在项目 classpath.Removing 中存在此依赖项的所有不同版本，只保留一个将解决 issue.By 默认值，您可以尝试使用 javax.mail.api-1.4.5 随 EAP 6.4
